Describe the bug

DGPU isn't using full 100W consistently with Delta 240W PD 3.1 charger while in performance mode. It will momentarily use it when battery reaches full, but when it's charging/discharging it doesn't reach the 100W limit.

While in Balanced mode connected to the 240W charger, the DGPU uses up to the 100W limit consistently.

Steps To Reproduce

Steps to reproduce the behavior:

1. Discharge framework 16 battery and open a GPU intensive game while in performance mode. I used total war warhammer 3 (proton experimental)

2. Open a system monitor software and look how much power DGPU uses while charging. I used AMDGPU_TOP.

3. When DGPU has hit charging cap, look at average and see it has increased. It will potentially hit 100W for a brief moment and then drop back down to around 75W. The DGPU core and memory speeds will fluctuate wildly.

Expected behavior

While laptop is set to performance mode and charging connected to a 240W PD 3.1 charger, The GPU should be able to hit 100W consistently and possibly be capped up to 120W while in performance mode connected to a PD 3.1 240W charger.

Screenshots

Image 1 is laptop gaming while in performance mode. Battery is discharging from 80% to 70% and system is unplugged.

Image 2 is system (Set to performance mode) is plugged in to 240W delta PD 3.1 charger, while battery is recharging from 70% to 80%.

Image 3 is system (Performance mode) charged to 80% (The set charging limit) while connected to the 240W delta charger.

Operating System (please complete the following information):

• OS/Distribution: Ubuntu
• Version: 24.10
• Linux Kernel Version: 6.13-rc2

Additional context

With framework 180W adapter connected, DGPU uses about 100W constant. Clock and memory speed remain stable.

With 240W PD 3.1 adapter connected, DGPU uses about 74-83W with constant fluctuations, and the clock and memory speeds are all over the place.

I can recreate this on windows. With the Framework 180W PSU, I can consistently run the dGPU at 80-90W. On the Delta 240W PSU, the dGPU is constantly throttling at 30W.

Framework 16
Ryzen 7 7840HS
Radeon RX 7700S
64GB RAM
2TB SSD
Windows 11 24H2
BIOS 3.05
2024-10-2 driver pack installed

Originally had BIOS configured to limit battery charge to 90%. Suspected that BIOS might be limiting dGPU power draw to charge the battery, but since the battery could never reach fully charged my performance suffered. Set max charge to 100%, disabled adaptive battery saver, no change. Only switching to OEM 180W PSU with Balanced power mode seems to allow dGPU to run at up to 100W.

Thanks! We will investigate this and try to fix in the next release.

@kiram9 - Same issue as OP - when below 90% I notice EXTREME frame pacing issues. My dGPU shows its using 75-100w (in fluctuations) and I think that is why the frame pacing is happening. I tried with different GPU power modes - but automatic is the most stable - as the other options are worse.

Same bios - 3.05

If any logging is needed, please let me know!

I wrote about that issue first on 12/1/24 in the Framework Forum and tried a Fault analyzes with overwriting Smartshift and STT/stapm Values with Smokeless_UMAF and even tried reinstalling Windows and installing bazzite OS. It doesn't depend on the installed OS. https://community.frame.work/t/framework-laptop-16-ryzen-7040-bios-3-05-release/60735/70?u=psierra117 I Suspect some recent changes to the EC Configs to be responsible, as the STT/Stapm Settings do not correspond to any changes I made with Smokeless_UMAF so the Bios/Uefi is not controlling the Power Management. And also many People already have told, that with 3.05 the Framework 16 is draining battery in "Balanced" Mode on the 180w Charger which was not happening in 3.04 or 3.03. So changes introduced in 3.05 seem to be responsible.

[knipp30]

To add to this. as it seems that the issue still relates to power negation

when using the 240w charger, when gaming in performance or balanced mode, if the battery discharges below 100%, the games start frame pacing issue I shared in the video above.

Right now, to game anything close to consistent, I have to game in power save mode.

Any update to the progress of resolving this?

I have some more information:

My current system configuration is set up with Linux mint 22.1 using kernel 6.14-rc2.

The issue still persists with the battery disconnected from the system while it is in performance mode.

Without the battery, it also exhibits the same issue in the balanced power mode:

In power saver mod with the battery disconnected, the frame rate is significantly better averaged (even while capped at 70W) and the GPU memory clock speed doesn't change for the duration of the benchmarch, only the SCLK.

After a lot of frustration with throttling on the 180W charger I got myself a Delta 240W. In Balanced mode, I can go for 2-3hrs in a demanding game until suddenly performance/GPU power throttles and the battery is at 95%. Whenever I check the battery earlier than that it reads 100%, so it's as if it's just deciding to let the battery drain 5% at some point and then the GPU power throttles as a result until it's recharged. Far from ideal when you're in the middle of playing with friends and suddenly the game is unplayable, but the alternative is the 180W charger letting the battery drain like crazy and trying to keep it from going too far.

As someone who basically never uses a laptop on battery in the first place, allowing battery conditioning logic to repeatedly tank my experience is a complete waste. If I could rollback to a previous BIOS I would, but the forum thread for that doesn't record anyone doing so successfully. Please resolve this ASAP. Thanks

Unfortunately, Framework has stated that you cannot roll back the bios version from 3.05...

"Important Note

After updating to this version you will not be able to downgrade to an earlier version."
